When you receive udp packages they look something like: {udp,{socket,<0.41.0>,#Port<0.12>,inet_udp}, {203,102,230,172}, 1024, [1,2,3,4,5,6,7]} I suppose the "1024" means something, I asumed its the port number but its not, its always 1024 and increasing with the number of open ports so what does it represent?
